i shoot right handed. for whatever reason, my horizontal pin adjustment is FAR to the left. i am left eye dominant, but i block or close that eye when i shoot so that cant be it. on my new sights, when it's adjusted properly it (just like the old one ) extends WAY left, so much so that there is very little of the horizontalsupport bar left in the clamps that hold it in place.

here's the problem-after about ten shots, it vabrates loose, and i gotta sight it in all over again. any ideas how i can keep the bugger locked in place? also anyone have any idea why i have to adjust so far the the left?
